We have the small version (7 fins?) of this and as mentioned in Choice Magazine, it has 'borderline heating'. If we switch it on at 10pm our smallish 4x4 bedroom will be almost warm by 4am...as compared to the cheap Goldair model which warms up the kids room in no time at all. Also I find it very difficult to read the dials against the black background, so poor design. Next time I'll read Choice before I buy.
Oh yes, the enclosed design also means our toddler can drop plastic toys into the tube holes.

Great value heater with a timer function that lets you turn program it for various times during the day. I live in Canberra where it's freezing, and I have two of these heaters - they keep the house toasty (3br house). You may wish to have a third heater depending on the layout of your house.

It managed to heat up small-to-medium rooms quickly, and held a good temperature. Controls are easy to operate, no problems there. But then it began shorting out and shutting itself off. We've tried multiple wall sockets in different areas of the house, trying to isolate the problem and the unit continues to shut itself down, often tripping the surge protector with it.
